Fluorescence micrograph of CHO cells expressing the hA3AR following incubation with 50 nM MRS5449 for the time as indicated: A) 15 min; B) 60 min; C) 120 min; D) 180 min. hA3AR-expressing CHO cells preincubated with 10 μM MRS1220 (E) and hA3AR-expressing CHO cells in the absence of any fluorescence ligand (F) were used as controls, but significant cell fluorescence was not observed.
